Abstract: The subject of this academic research work is production of ashy unburned gravel according to technology of two-bath silicatization with the usage of local fly ashes and bottom-ash mixtures of heat power plants in combination with liquid glass and calcium chloride which are non-inferior according to compression strength characteristic in cylinder and density to cement-ash gravel. Currently in building precast and mass concrete are extensively used for production of which natural aggregates are used. Unburned ashy gravel is used as a coarse aggregate for constructional and construction-insulating concretes. In Kuzbass, there is a lack of coarse light aggregate which is needed for organization of production of sectional envelope constructions and low- and high-rise cast-in-place house building constructions. In the course of the study, we have defined influences of some technological factors and approaches of ashy gravel’s production on its strength characteristics. The results of this researches allowed suggesting technology for manufacturing ashy gravel according to the scheme of two-bath silicatization as well as to establish optimal technological parameters and regimes at which strength characteristics allow using it as an alternative effective aggregate for light concretes. Usage of wastes of fuel, energy and chemical industry for production of building materials, vacation of lands, occupied by storage of such wastes help resolving ecological issues that are related with environmental pollution of Siberian region.
